Electric Fan wiring diagram

[uglymug]

Hi guys , as requested before , I need a wiring diagram for the non working electric fans . Basicaly found out part of ciruit but need help in where the 85pin goes to . It says it needs to go to a switchable ign source , but do not want to go that route as wiring is not that good on the old girl . Need it to go to the battery .

So can someone enlighten me on how to do this ...............cheers
